VEHICLE VISION SYSTEM WITH ENHANCED LANE TRACKING
First Claim
1. A driver assistance system for a vehicle, said driver assistance system comprising:
- a camera disposed at a vehicle and having a field of view forward of the vehicle;
a control comprising an image processor that is operable to process image data captured by said camera;
wherein, responsive to processing by said image processor of image data captured by said camera, said image processor is operable to determine lane markings demarcating the lane in which the vehicle is traveling; and
wherein, responsive to processing by said image processor of image data captured by said camera and responsive to at least one of (i) a map input from a digital map to said control and (ii) a location input from a global positioning system to said control, said control estimates a path of travel for the vehicle to maintain the vehicle in the lane in which the vehicle is traveling in situations where the lane markings demarcating the lane in which the vehicle is traveling are not readily determinable.

Abstract
A driver assistance system for a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle. A control includes an image processor that is operable to process image data captured by the camera. Responsive to processing by the image processor of image data captured by the camera, the image processor is operable to determine lane markings demarcating the lane in which the vehicle is traveling. Responsive to processing by the image processor of captured image data and responsive to at least one of (i) a map input and (ii) a location input, the control estimates a path of travel for the vehicle to maintain the vehicle in the lane in which the vehicle is traveling in situations where the lane markings demarcating the lane in which the vehicle is traveling are not readily determinable.

15. A driver assistance system for a vehicle, said driver assistance system comprising:
-
a camera disposed at a vehicle and having a field of view forward of the vehicle; a control comprising an image processor that is operable to process image data captured by said camera; wherein, responsive to processing by said image processor of image data captured by said camera, said image processor is operable to determine lane markings demarcating the lane in which the vehicle is traveling; wherein, responsive to processing by said image processor of image data captured by said camera and responsive to (i) a map input from a digital map to said control and (ii) a location input from a global positioning system to said control, said control estimates a path of travel for the vehicle to maintain the vehicle in the lane in which the vehicle is traveling in situations where the lane markings demarcating the lane in which the vehicle is traveling are not readily determinable; wherein said control estimates the path of travel for the vehicle responsive to the location input that provides the vehicle'"'"'s current geographical location information from the global positioning system of the vehicle; and wherein said control estimates the path of travel for the vehicle responsive to the map input that provides road information pertaining to the road along which the vehicle is traveling. - View Dependent Claims (16, 17)

18. A driver assistance system for a vehicle, said driver assistance system comprising:
-
a camera disposed at a vehicle and having a field of view forward of the vehicle; a control comprising an image processor that is operable to process image data captured by said camera; wherein, responsive to processing by said image processor of image data captured by said camera, said image processor is operable to determine lane markings demarcating the lane in which the vehicle is traveling; wherein, responsive to processing by said image processor of image data captured by said camera and responsive to at least one of (i) a map input from a digital map to said control and (ii) a location input from a global positioning system to said control, said control estimates a path of travel for the vehicle to maintain the vehicle in the lane in which the vehicle is traveling in situations where the lane markings demarcating the lane in which the vehicle is traveling are not readily determinable; wherein said control estimates the path of travel for the vehicle responsive to vehicle information, and wherein the vehicle information comprises at least one of (i) vehicle speed, (ii) vehicle differential wheel speeds and (iii) vehicle yaw rate; and wherein said driver assistance system maneuvers the vehicle along the estimated path of travel. - View Dependent Claims (19, 20)
